21. Install the end cover (D), and tighten the three special bolts (E) and the 6 x 1.0 mm bolts (F) (12 bolts).
22. Install the harness clamp bracket (G) on the end cover.
23. Move the selector control shaft (A) from the P position to the N position by turning the selector control shaft on the torque converter side.
    NOTE: Do not squeeze the end of the selector control shaft tips together when turning the shaft. If the tips are squeezed together it will cause a faulty shift position signal or position due to the play between the selector control shaft and the transmission range switch.
